Saving required Commerce Fieldgroup Panes field value to optional user profile field.
For the independent signup I want to keep only email field, so that I have made some fields which are optional in there.
But if somebody checkout after buying some product I have to gather many info from him which match user profile info fields, so I want to save them on checkout. But I am not able to find the way doing it.
If I choose a field as required at user profile then I can do it by modyfying the rule as the field appears...but if it's optional there is no way adding more field...
Can anybody help on this ?
